Nemesia plant named ‘Kirine-50’

ABSTRACT

A new and distinct cultivar of  Nemesia  plant named ‘Kirine-50’, characterized by its upright, outwardly spreading and uniformly mounded growth habit; freely branching and flowering plant habit; large red purple-colored flowers that are fragrant; relatively tolerant to high temperatures; and good garden performance.

Botanical designation: Nemesia hybrida.

Cultivar denomination: ‘Kirine-50’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant, botanically known as Nemesia hybrida and hereinafter referred to by the name ‘Kirine-50’.

The new Nemesia plant is a product of a planned breeding program conducted by the Inventor in Tochigi, Japan. The objective of the breeding program is to create new Nemesia cultivars with good vigor and attractive flower coloration.

The new Nemesia plant originated from a cross-pollination made by the Inventor in February, 2007 in Tochigi, Japan of two unidentified selections of Nemesia hybrida, not patented. The new Nemesia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Tochigi, Japan in October, 2007.

Asexual reproduction of the new Nemesia plant by terminal cuttings in a controlled environment in Tochigi, Japan since November, 2007, has shown that the unique features of this new Nemesia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Nemesia have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Kirine-50’. These characteristics in combination distinguish ‘Kirine-50’ as a new and distinct cultivar of Nemesia:

-   -   1. Upright, outwardly spreading and uniformly mounded growth         habit.     -   2. Freely branching and flowering plant habit.     -   3. Large red purple-colored flowers that are fragrant.     -   4. Relatively tolerant to high temperatures.     -   5. Good garden performance.

Plants of the new Nemesia can be compared to plants of the parent selections. Plants of the new Nemesia are more vigorous and have larger flowers than plants of the female parent selections and smaller flowers than plants of the male parent selection.

Plants of the new Nemesia can be compared to plants of the Nemesia ‘Kirine-12’, disclosed in U.S. Plant Pat. No. 18,269. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Nemesia differed primarily from plants of ‘Kirine-12’ in the following characteristics:

-   -   1. Plants of the new Nemesia were more mounding and denser than         plants of ‘Kirine-12’.     -   2. Plants of the new Nemesia and ‘Kirine-12’ differed in flower         color as plants of ‘Kirine-12’ had lighter and paler-colored         flowers.

Plants of the new Nemesia can also be compared to plants of the Nemesia ‘Inuppink’, disclosed in U.S. Plant Pat. No. 17,472. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Nemesia differed primarily from plants of ‘Inuppink’ in the following characteristics:

-   -   1. Plants of the new Nemesia were stronger and sturdier than         plants of ‘Inuppink’.     -   2. Plants of the new Nemesia had larger flowers than plants of         ‘Inuppink’.     -   3. Plants of the new Nemesia and ‘Inuppink’ differed in flower         color as plants of ‘Inuppink’ had lighter-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Nemesia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Nemesia.
